Transitivity in choice, in its simplest definition [25], states that if an individual prefers option A over B and B over C, then it also prefers A over C. However, the level of expression of transitivity depends on whether options can be ranked on an ordinal or an interval scale [26]....

In addition, a number of environmental factors impinge on female and male behaviour (for a wide ranging discussion, see 13, 18). Mating decisions are often summarised under the broad categories of preference and choice [19]. The distinction between these categories, both conceptually and ...

In mate choice experiments, both sexes preferred large mates irrespective of own body size suggesting mating preferences are not size-assortative. Especially males were highly selective for large females, probably because female body size signals direct fitness benefits. However, when potential mates were...
If male SSB functions through sexually selected male–male competition, it should be more evident within Male-biased regimes, where reproductive competition is nine times greater, than in the Female-biased regimes. By contrast, if SSB exists due to inaccurate mate choice, it should be reduced in...
From the information above, it is easy to tell why a man and van service is the best choice for students and people with fewervaluables. Ensure to take your time before choosing any service provider. Also, have the right budget to avoid inconveniences or scams. Scammers usually target their...
Patterns of mate choice in this woodrat system appear to be strongly impacted by body size and aggressive behavior. In particular, females of the smaller-bodied species rarely interact with the relatively large heterospecific males. In contrast females of the larger-bodied species accept the relative...
First, it provides an indicator of the underlying characteristic of healthiness. Second, the signal likely is effective, because workout posters may be perceived as more attractive potential partners due to their greater inferred healthiness and mate value. Third, working out is costly in terms of...
Male mate choice has recently been reported in some animals with male–male competition. In the laboratory, we examined whether males choose their mates based on female quality that was indicated by body size and/or days to prenuptial molt, and the effects of female quality on male–male compe...
